LABEL PASTING MACHINE Filed June 1a, 192? 5 Sheets-$11,883 2 PatentedSept. 8, 1931 UNITED STATES MARIO VOLI, OF PHILADELPHIA, PENNSYLVANIALABEL BASTING MACHINE Application filed .Tune 16, 1927.. Serial. No.199,214.

My invention relates to a new and useful improvement in label pastingmachines, and has for its primary object toprovide an exceedingly simpleand effective machine of this description by which paste may be rapidlyand accurately applied to one side of a label, and the label thustreated delivered toa table or surface upon which it may be applied to acan or other container.

A further object of my invention is toprovidemeans for accuratelyspacing the feed rolls relative to the paste roll and provide for thechanging ofthis spacing for determining the exact amount of pastetobeapplied to the I5 feed roll for transference to the labels.

A still further object of my invention 1s to provide means for takingofi the labels from the feed rolls.

With these and other ends view, my invcntionconsists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims;

In order that those skilled in the art to 2 which this inventionappertains may understand how to make and use the same, I will: describeits construction indetail, referring by numerals to the accompanyingdraw ngs forming a part of this application rnwhicl'l:

Fig. 1 is a rear elevation of the mach ne built in accordance with myimprovement.

Fig. 2 is a plan view of Fig. 1.

Fig. is a detailed plan of the takeoff for V p the lower feed roll.

- Fig. l is a detailed view pf the lower feed roll.

Fig. 5 is a sectional end elevation of the machine, the driving gearbeing partially broken away.

Fig. 6 is a detailed view of the train of gearing for causing the pasteand feed rolls to revolve in unison.

Fig. 7 is an end view of the-paste reservoir. Fig. 8 is a plan view ofthe portion of the: paste reservoir. I

Fig. 9 is a perspective of a portion. of thefeed table, showing theattaching bracket.

In carrying out my invention as herein embodied, 10 represents a tank orreservoir, 5 the interior of which is divided into two compartments 11and 12,- by the partition 13", and this'tank is supported upon suitablelegs, such. as indicated at 14.

One side of the tank. has formed therein a bearing slot 15, the lowerportion of the latter being of less width than the upper portionthereof, for the purpose hereinafter exiplained, and the opposite sideof the tank'has formed therein the bearing slot 16 which latter is. ofthe same width through. its height.

17 represents a shaft, the inner end of. which is jjournalled in thebearing block 18, which latter is fitted within the slot-'16, while theouter end of this shaft is journ'alled in the lower and narrow portionof the slot 15; this shaft carries the dipping roll 19.

also represents: a shaft which is fournalle'd in the hangers 21, and on.this shaft is carried the coating roll 22, and this roll is a spacedrelative to the roll 19, as hereinafter set forth.

23 represents two frames, each of which is pivoted at 24 to one side" ofthe tank, and these frames carry the hangers 21 and are made adjustableby the screw rods 24, which latter are threaded in the outer ends oftheframes, and are provided with thumb holds" 25 for their propermanipulation.

Thus, it will be seen that the roll 22 may be raised or lowered andproperly aligned by" theproper manipulation of the screw rods 24;

26" represents a shaft upon which the discs- 27 of the skeleton presserroll are positioned apart by the spacers 2'8, and this skeleton roll orthe discs thereof contact with the coating roll 22. by gravity, theshaft 26' being iou'rnalled in slotted bearings in the frames 23', topermit free vertical movement of this shaft.

29 represents two coil springs, the lower ends being, attached to thestuds 30, while their upper ends are attached to the outer ends of theframes 23 so as to hold theframes ping and coating rol ls apart, such aswhen heavy glue is to be used, I provide the arms 31 which are pivotedto the sides of the tank at 32 connected by the screw rod-s 33- with theframes 23, and these arms may be seated upon the shoulders 34 of thedipping roll and the corresponding shoulders of the coating roll 22 mayrest upon these arms, thus accurately determining the spacing betweenthe paste roll and the lower feed roll, which in turn determines theexact thickness of the paste applied to the lower feed roll, and wherethis is of thick material, such as heavy glue, it will be forced uponthe feed roll in an even and predetermined thickness which is essentialin certain classes of work.

35 represents a combined table and cover and is provided with dependingbrackets 36 which have open end slots 37 therein for sliding over thebolts 38, by which this bracket is attached to one wall of the tank, asclearly shown in Fig. 1. The inner portion of the table 35 serves as acover for the storage compartment formed at the front portion of thetank by the partition 13, this compartment serving to hold a reservesupply of paste or glue.

Labels placed upon the table 35 and fed forward by hand will be receivedby the coating rolls 22 and the presser roll 27 and carried rearward,during which movement the paste or glue will be applied to the underside of said labels by their contact with the roll 22, and from thencethese labels will pass on to the receiving table 39 which has its innerend slightly offset so as to properly bear upon the roll 22 and receivethe labels from this roll, so that such labels may be applied to cans orother containers upon the table 40 which latter is hinged to the rearwall of the tank and provided with a supporting arm 41 for holding it inposition permitting it to be swung downward. One end spring 42 isconnected to the receiving table 39, the other end of said spring beingconnected to the pin 43 upon the outer wall of the tank so as to givethe table 39 a spring pressure upon the roll 22. To provide against thelabels being carried around the presser roll 27, I provide a series offingers 44 which are pivoted upon the rod 45, these fingers bearing uponthe under side of the spacers 28 by the action of the spring 45.

46 represents the motor upon the shaft, which has the pinion 47 meshingwith the gear wheel 48, the latter being secured upon the shaft 17 andon this shaft is also secured a gear wheel 49 which meshes with the gear50 upon the shaft 20, and this gear 50 in turn meshes with the gear 51secured upon the shaft 26 so that all of the rolls are caused to revolvein unison and in the proper directions.

The teeth of the gears 49, 50 and 51 are such as to allow for theadjustment of the rolls relative to each other, without passing out ofmesh.

52 represents an inclined board located within the paste compartment ofthe tank, and so set as to cause the paste within this compartment to befed by gravity to the roll 19.

From the foregoing description, the operation of my improvement will beobviously as follows:

The proper amount of paste or glue is placed within the compartment ofthe tank in which the roll 17 is mounted and a suflicient reservequantity of such material is placed in the reserve compartment and themotor started so that by the revolving of the paste roll 19, paste willbe carried to the roll 22, when by one of the operators feeding labelsto the rolls, paste will be applied to the under side thereof, while theother operator manipulating cans or other containers supported upon thetable 40 will revolve these labels and manually apply them to thecontainers.

On account of the simplicity of the construction and operation of themachine, these operations will be carried on rapidly, thus re ducing thelabel cost, while producing highgrade work.

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be varied within the limits ofthe appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis:

1. A label pasting machine comprising a tank, two frames pivoted attheir forward ends to the upper forward portion of the tank, means toselectively limit the downward movement of said frames, hangersdepending from said frames, a coating roll journalled in said hangers, apresser roll journalled in the frames and coacting with the coatingroll, a dipping roll journalled within the tank for coaction with thecoating roll, and means to transmit motion to the several rolls.

2. A label pasting machine comprising a tank, two frames pivoted atopposite sides of the tank, hangers depending from said frames, acoating roll journalled in said hangers, a dipping roll journalled inthe tank for coaction with the coating roll, a presser roll carried bythe frames and including a shaft, discs mounted on said shafts, spacersmounted on said shafts between the several discs to maintain them indesired spaced relation, a rod carried by the frames, a series offingers pivoted upon said rod and projecting between the discs, andmeans for resiliently holding said fingers against the spacers.

In testimony whereof, I have hereunto affixed my signature.
